Auto matching items

Hi everyone, I’m trying to implement a matching solution in monday.com onlyno external integrations allowed (no Make/Integromat, Zapier, API scripts, custom apps, or any third-party tools).

I have two boards:

Board A (requests) — each item has:

  • Min (number)

  • Max (number)

  • additional fields that must match Board B (e.g., Type / Region / Category / Status and possibly more)

Board B (options) — each item also has:

  • Min (number)

  • Max (number)

  • the same matching fields (Type / Region / Category / etc.)

What I need

For a given item in Board A, I need to find the items in Board B that match based on multiple criteria, including:

  1. Range overlap (dynamic ranges, can be large — up to millions):
    Match when:
  • B.Min <= A.Max and

  • B.Max >= A.Min

  1. Additional exact matches (examples):
  • B.Type = A.Type

  • B.Region = A.Region

  • etc.

What I do NOT want / constraints

  • I do not want to connect Board A to all items in Board B first and then filter/validate.

  • Ranges are dynamic (not fixed buckets/tags).

  • Again: NO external integrations.

Question

Is there a way to do this inside monday.com only (including the new Workflows and/or AI blocks if needed), so that for an item on Board A I can get the list of matching items on Board B (or otherwise identify them)?

If yes, I’d appreciate the exact workflow/action/feature name and an example of how to configure the conditions.
